The AV-40 is a professional saw sharpening machine. It will sharpen face, top and side grind saw blades ranging from 1-7/8″ to 30″ diameter. It will also sharpen many different cutting tools such as, raised panel and profile cutters, anti-kick back router bit and shaper cutters without motor interference; something few saw blade grinders can offer.
The motor maintains a wheel RPM of 3450 – something essential when grinding carbide tooling. Other carbide saw grinders on the market actually slow down or stop the wheel when grinding. This is why Thorvie International manufactures a modified version of the AV-40 motor designed to be used as a replacement on our competitor’s equipment. (A 220 volt 50hz 2850 rpm available for foreign countries.)
The AV-40 saddle assembly has four bearings, while many other grinders typically only have three. This allows the AV-40 saw blade and tool holder to give you precision grinding performance as the saddle bearing assembly is solid with no play whatsoever.
When comparing value in systems the AV-40 saw sharpening machine is far less expensive. Plus, when buying manufacturer direct from Thorvie International you’ll save 40% or more!
When looking into a saw blade sharpening machine, make sure the machine is able to face and top grind a saw blade. If you only face grind a saw blade you are only doing half the job and you will not get professional sharpening results. Top grinding is more important than face grinding. When you top grind an alternate bevel saw blade, this allows to sharpen every tooth to the same height making sure the blade is balanced. Even a brand new alternate bevel saw blade from the factory can be 3 to 5 thousandths different from the left to the right cutter teeth. The higher teeth will do more of the cutting than the lower teeth. By top grinding and balancing the blade properly, each tooth will be cutting equally through the wood and the saw blade will cut better than new.
With its compact size, it takes up minimal bench space and can serve as an excellent mobile unit.
The AV-40 saw sharpening machine is one of the easiest and fastest machines to learn how to set up and operate.
